About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX325-40
The AirTAC SAIJ200X325-40 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, featuring a robust 200 mm bore. It integrates a rear stroke adjuster that permits you to trim the effective travel by up to 40 mm, creating a usable stroke window of 285-325 mm for precise end-position calibration. Delivering a substantial push force of 15708 N at 0.5 MPa, it is built to move massive loads. This specific configuration incorporates a SUS304 stainless steel rod for superior corrosion resistance and utilizes a PT tapered G3/4 port thread.
Because the nominal 325 mm stroke is substantial, the 40 mm carbon steel piston rod diameter demands an external guide to prevent excessive side-loading and premature seal wear. The extruded aluminum barrel includes sensor grooves on both sides, allowing straightforward tracking when paired with CMSE reed or DMSE electronic sensors. The rear adjuster acts purely as a mechanical stop to set the retract position and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX325-40 Is Used
Heavy Press Tuning
Dial in the exact 285-325 mm retract position during heavy press commissioning without swapping out the entire cylinder or fabricating external shims.
Product Size Changeover
Quickly adjust the end-stop by up to 40 mm on a production line when transitioning between large product variants, minimizing machine downtime.
Large Assembly Positioning
Leverage the 15708 N push force at 0.5 MPa to move heavy pallets or fixtures, using the rear screw to fine-tune the final resting position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX325-40 the Right Cylinder?
Selecting this 200 mm bore model is appropriate when an application requires moving loads that exceed the 10053 N push force of the smaller 160 mm variant at 0.5 MPa, provided the pneumatic supply can sustain the increased volume. The 40 mm adjustable range is ideal for product changeovers on a line, enabling operators to dial in a new end-stop distance without physically swapping the cylinder or adding external hard stops. For applications requiring true load-holding in the event of air pressure loss, a standard SAIJ is insufficient; consider the SAIL air-released lock or BSAI clamp-lock series instead.
When replacing an ISO 15552 cylinder, verify the 200 mm bore, 325 mm stroke, 40 mm adjustment window, PT G3/4 port, and mounting interface. The SAIJ series supports a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR brackets. Given the 325 mm stroke, always ensure proper external guidance to support the rod and prevent binding during the 285-325 mm travel window.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ200 Adjustable Cylinder SAIJ200BX325-40 FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. At the maximum operating pressure of 1.0 MPa, the push force reaches 3204 kgf.
The rear adjuster screw allows you to mechanically shorten the 325 mm nominal stroke by up to 40 mm, providing an effective travel window of 285 to 325 mm. This stopper fine-tunes the end position but does not lock or hold the load without continuous air pressure.
